Description
Technical field
The present invention relates to sealing material, belong to the axostylus axostyle sealing material technical field having rotary motion for pump class, valve, speed reduction unit etc.
Background technology
The existing pump packing adopting sizing specification, is filled in the stuffing box of pump more.Although this sealing means is comparatively easy, effect to a certain extent can be played, but the friction still also existed between this type of packing and pump shaft to a certain degree, even if the packing that frictional coefficient is very little, it is also surprising with the thermal value of the synapsis that is coupling, and therefore often needs to coordinate cooling system cooperation.Life-time service is also quite serious to bearing wear simultaneously, and life-time service can cause permanent injury to bearing.
Muddy packing------also claims: " pouring-in wadding " is equipped with special grease and lubrication by high-performance fiber of new generation, refining senior " packing "---wadding, arbitrary dimension, arbitrary shape, very easily install, just can direct injection by special High Pressure Gun, traditional packing need not be resembled, need precut, the packing box seal of any size can be suitable for.
Installing wadding needs to the certain prestress of filler, kick the beam the gap can caused between filler and bearing, overweight meeting causes filler and bearing to extrude tension, cause filler and bearing friction to produce large calorimetric and propose the appearance of the phenomenons such as vibrations with pump, therefore rationally Shi Hanzhang just can make filler and bearing good combination, but how could reasonable Shi Hanzhang, it is suitable that great power is only, if above-mentioned situation occurs excessive how about the avoiding of prestress.
Summary of the invention
The technical problem to be solved in the present invention is, not enough for prior art, proposes a kind of low-friction coefficient wadding and preparation method thereof.
The present invention is the technical scheme solving the problems of the technologies described above proposition: a kind of low-friction coefficient wadding, is made up of following mass percent:
Vegetable fibre 20% ~ 40%
Inanimate matter 20% ~ 30%
Treating compound 5% ~ 10%
Lubricant 5% ~ 15%
Thickening material 5% ~ 15%
Wherein,
Described vegetable fibre is the mixture of in castor-oil plant line, linen thread, ramie line or jute yarn at least two kinds;
Described inanimate matter is in graphite, molybdenumdisulphide or silicon-dioxide two kinds;
Described treating compound is the one of Trimethoxy silane, silmethylene or purity 99% in ptfe emulsion;
Described lubricant is the one that castor-based lubricating oil, mineral base oil or PAO gather in the rare hydrocarbon synthetic oil of ɑ;
Described thickening material is natural polymer and derivative thereof, comprising: one or more in starch, gelatin, sodium alginate, casein food grade, guar gum, chitosan, Sudan Gum-arabic, xanthan gum, soybean glue, natural rubber, lanolin, agar.
In described vegetable fibre, each composition quality percentage composition is: 10% ~ 60% castor-oil plant line, 15% ~ 40% linen thread, 0 ~ 20% ramie or 0 ~ 20% jute.
In described inanimate matter, each composition quality percentage composition is: 35% ~ 65% graphite, 0 ~ 35% molybdenumdisulphide or 0 ~ 35% silicon-dioxide; The particle diameter of described inanimate matter is 2000 ~ 3000 orders.
Preparation method's step of described low-friction coefficient wadding is as follows:
(1) described vegetable fibre normal temperature to be immersed in described treating compound 24 ~ 48 hours;
(2) take out the vegetable fibre infiltrated in step (1) and carry out chopping process, the plant fiber length after chopping is less than 5mm;
(3) in the first Scattered Kettle, add described inanimate matter and described lubricant successively, 800 revs/min of high-speed stirring, mix 10 ~ 15min;
(4) in the second Scattered Kettle, add the mixture of acquisition in the vegetable fibre after chopping and step (3) successively, abundant mixing, after 800 revs/min of high-speed stirring, then in the second Scattered Kettle, add thickening material and with 50 ~ 150 revs/min of stirring at low speed until between the two without obvious layering;
(5) mixture obtained in step (4) is carried out evaporation process with 50 ~ 80 DEG C, make the mass percent of water in final mixture between 13% ~ 25%.
The present invention adopts the beneficial effect of technique scheme to be: the present invention is cooperatively interacted by the close or similar vegetable fibre of character of use and treating compound, treating compound is better infiltrated through in vegetable fibre, to reduce the frictional coefficient of vegetable fibre used, be mixed into pulverous electrodeless material simultaneously, the gap in vegetable fibre is clogged with this, the problem that the contact surface reducing to cause in gap is uneven, because filler frictional coefficient of the present invention is less, bearing and filler with the use of time, even if the prestress being applied to filler radial direction is bigger also can not produce larger frictional force between bearing and filler, thus avoid in friction that position is overheated causes damage of the bearing.Take when preparing this wadding first to infiltrate the decomposite step of rear chopping simultaneously, stir with shorter vegetable fibre, reduce the burden in whipping process, stirrer brought; Final evaporation process, significantly reduces water-content, to preserve.
Embodiment
Embodiment
A kind of low-friction coefficient wadding of the present embodiment, is made up of following mass percent:
Vegetable fibre 20% ~ 40%
Inanimate matter 20% ~ 30%
